I got the idea of making a synthesizer with the Picaxe. I googled around and it seems to have been done already though I have not found a finished project. I was thinking of using a 14M2, using the four PWM pins to have four oscillators.
The plan was to use potentiometers to adjust both the frequency and pulse width of the PWM. I tried bread boarding it using a single PWM output, but it did not work according to plan. Adjusting the frequency worked in a weird way with the sound cutting out and the pulse width adjustments were problematic too. I will try again tomorrow. In the mean time, does anyone have any ideas about how to make this idea better or experience with something similar?
